Speed of a satellite in low orbit
Open answerA satellite is in circular orbit around the Earth at a radius r = 6,800 km = 6.8x10^6 m. The mass of the Earth is given as M = 5.97x10^24 kg and G = 6.67x10^-11 N.m^2/kg^2. Calculate the speed v of the satellite (formula v = sqrt(G*M/r)) and explain why this speed does not depend on the mass of the satellite.
